Abstract

PURPOSE:To adjust laser output at the maximum level of the standard stably by a method wherein spatter from a mirror supporting body is controlled by the results of comparison between the detecting voltage of the laser output and reference voltage. CONSTITUTION:When turning a power source switch 19 ON, the laser tube 1 normally discharges using a mirror supporting body 2' as an anode and cathodes 4, 4' as cathodes. Difference voltage between the detected voltage of laser output 18 by means of a light detector 5 and a reference power source 11 is amplified by means of a comparison amplifier 8 to turn a controlling switch 13 ON, and the laser tube 1 forms another discharge path using the cathodes 4, 4' as anodes and a mirror supporting body 2 as a cathode. Consequently, when the supporting body 2 spatters, a spattering film adheres to a mirror 3, and laser output lowers and reaches the maximum level of the standard, difference between two input to the amplifier 8 expires, and output from the amplifier 8 reaches zero. Thus, the switch 13 is turned OFF, and discharge between the cathodes 4, 4' and the supporting body 2 expires. When the output 18 increases due to normal discharge, the switch 13 is turned ON again.
